Skincare Compositions

ABSTRACT

This invention relates to skincare compositions, in particular compositions effective in the treatment of acne vulgaris, and to methods of treatment of the skin that involve the application of such compositions, wherein the compositions comprise salicylic acid or a salt thereof in combination with at 2 actives selected from the group consisting of lactic acid or a salt thereof; glycyrrhizinic acid or a salt or derivative thereof; bisabolol; cetylhydroxyproline palmitamide; allantoin; niacinamide; and epilobium angustifolium extract.

This invention relates to skincare compositions, in particular compositions effective in the treatment of acne vulgaris, and to methods of treatment of the skin that involve the application of such compositions.

Acne vulgaris (acne) is a chronic inflammatory condition of the pilosebaceous units of the skin, which is particularly prevalent in adolescents. The condition generally causes the formation, on the skin, of comedones, red papules, pustules and sometimes cysts. This is unsightly and furthermore, if untreated, acne can lead to scarring of the skin. The major causes of acne are thought to be an increase in sebum production, an increased presence of propionibacterium acne (P. acne), blockage of the pilosebaceus duct and the production of inflammation.

Salicylic acid is known to be effective in the treatment of acne. It is a topical keratolytic agent that works by dissolving the intercellular cement that holds epithelial cells together. Salicylic acid is used in a variety of over-the-counter acne remedies.

In order to improve the efficacy of topical acne treatments, it is desired to formulate salicylic acid with one or more control agents to regulate the inflammatory effects sometimes observed, such as local skin peeling and discomfort such as burning and skin reddening.

Surprisingly, it has now been found that skincare compositions comprising salicylic acid and at least two or more chosen actives have improved therapeutic efficacy in the treatment of acne. Said skincare compositions have both the ability to treat acne and reduce the appearance of redness on the skin.

Thus, according to a first aspect of the invention there is provided a skincare composition suitable for topical application to the skin, the composition comprising salicylic acid or a salt thereof, combined with at least 2 actives selected from the group consisting of:

-   -   lactic acid or a salt thereof;     -   glycyrrhizinic acid or a salt or derivatives thereof;     -   bisabolol;     -   cetylhydroxyproline palmitamide;     -   allantoin;     -   niacinamide; and,     -   Canadian Willowherb (epilobium angustifolium) extract.

It has been found that this treatment provides advantages over existing acne treatments, particularly in tolerance of the acne treatment by the skin. It may have an effect in reducing the severity of the acne and hence any associated marks or scarring that can occur; furthermore, cutaneous irritation may be reduced. Other measures indicating advantages are the reduction in inflammation in the affected skin and/or a soothing effect. A synergistic association between the chosen combination of ingredients may provide that a composition may have lesser amounts of each individual ingredient

Salicylic acid is preferably incorporated into the composition according to the invention as the free acid. However, the pH of the composition may, and generally will, be such that the salicylic acid exists in the composition in dissociated form. As the composition may well contain cationic counterions, the salicylic acid may then be thought of as being present in salt form. Alternatively, the salicylic acid may be incorporated into the composition already in salt form, eg as a salt with a Group I metal, such as sodium salicylate. As used herein, unless the context requires otherwise, any and all references to salicylic acid should be taken to encompass references to the acid and to dissociated forms and salts thereof.

In the case of solutions or dispersions, and gels, the composition will generally contain a solvent system or other continuous liquid phase. Such a system is preferably aqueous. However, mixed solvent systems may often be used with advantage. Such a mixed solvent system most preferably comprises water, in admixture with a co-solvent, most preferably a lower (eg C₁₋₆) alcohol, in particular ethanol and t-butyl alcohol.

Preferred aqueous systems comprise water in an amount of at least 25 percent by weight, more preferably at least 35 percent by weight, The upper limit of water will depend on the amounts of other ingredients incorporated in the composition so that the water may form the remainder of the composition up to 100 percent of the composition.

The composition may additionally comprise other components which will be well known to those skilled in the art. These include, for example:

a) Emollients—ingredients that help to maintain the soft, smooth and pliable appearance of skin. Such ingredients may function by their ability to remain on the surface of the skin or in the stratum corneum, and to act as lubricants, reducing or preventing flaking of the skin and improving the skin's appearance. Examples of emollients are isopropyl myristate, triglycerides of fatty acids eg lauric triglyceride or capric/caprylic triglyceride, such as the triglyceride available commercially under the trade name Miglyol 810 (Huls UK), and the polypropylene glycol ether of stearyl alcohol known as PPF-15 Stearyl Ether. Particularly preferred emollients are octyldodecanol and polysiloxane compounds, in particular those known as dimethicones.

b) Humectants or Moisturisers—ingredients intended to increase the water content of the top layers of the skin. Examples of such ingredients are glycerin, sorbitol, 1,3-butylene glycol and propylene glycol.

c) Surfactants—Surfactants may be used in compositions according to the invention as solubilisers, or as cleansing agents or foam boosters. Many different classes of surfactant may be suitable for inclusion in the composition according to the invention, and these will be readily apparent to those skilled in the art. Examples of suitable surfactants include anionic surfactants (eg sodium laureth sulphate, non ionic surfactants (eg cocoglucoside) cationic surfactants and/or amphoteric surfactants (eg cocoamidoproyl betaine). Polyethylene glycol ethers of alcohols such as isocetyl alcohol (eg Isoceteth-20), isostearyl alcohol (eg Isosteareth-20), cetyl alcohol (eg Ceteth-20), oleyl alcohol (eg Oleth-20) and cetearyl alcohol (eg Ceteareth-20).

d) Preservatives—ingredients which prevent or retard microbial growth and thus protect the composition from spoilage. Examples of preservatives include such as propylparaben, bronopol, sodium dehydroacetate, polyhexamethylenebiguanide hydrochloride, isothiazolone and diazolidinylurea.

e) Chelating agents or sequestering agents (sequestrants)—ingredients that have the ability to complex with and inactivate metallic ions in order to prevent their adverse effects on the stability or appearance of the composition, as described above. Examples of chelating agents are ethylenediamine tetraacetic acid and its salts, notably the dipotassium and especially the disodium or tetrasodium salt.

f) Abrasives—ingredients used to assist in the removal of unwanted tissue or foreign materials from the skin during application of the composition. Abrasives commonly comprise fine solid particles. Examples of suitable abrasives are polyethylene beads and aluminium oxide

g) opacifying agents such as clays (eg kaolin and bentonite) as well as titanium dioxide.

h) pH adjusters—Ingredients used to control the pH of the composition. Examples of pH adjusters are inorganic salts such as sodium hydroxide, and organic bases such as triethanolamine and arginine.

i) Conditioning agents, for example distearyldimonium chloride.

j) Perfumes and colourings.

The composition according to the invention may be applied and left on the skin to have the desired therapeutic effect or it may be applied and then rinsed off, for example with water for surfactant based formulations. The composition may be applied with the aid of a fibrous material, for example a pad or a wipe.

The purpose of the in vitro testing was to evaluate the potential anti-inflammatory action of compositions according to the present invention.

In vitro tests were carried out as follows:

-   -   take an irritant treated EpiDerm™ skin model. Initial         inflammation was measured by the cytokine release after exposure         to a single dose of irritant.     -   apply test compositions to the irritant treated EpiDerm skin     -   anti-inflammatory potential was then measured by reduction in         cytokine release     -   specifically, the levels of cytokines TNF-α, IL-6 and IL-8 were         measured to give a picture of the performance of the product         across the lifecycle of an acne event or related skin         inflammation.

Experimental design follows standard procedures, using phorbol-12-myristate 13-acetate (PMA) as irritant. Test samples were applied by pipette as solutions to the Epiderm tissue, and each sample was tested in triplicate against positive and negative controls. Anti-inflammatory activity measured by relative decrease in cytokine release in irritant-treated tissue compared to non-irritant treated tissue.

The separate active components of an example according to the invention were tested, along with some combinations in pairs and one combination lacking the salicylic acid. Where these actives were applied, they were in the same w/w ratio as in the example composition, example 9. The data shown in the table are the cytokine release values in pg/ml, wherein a lower figure shows a lower release rate of cytokines i.e. a lower inflammation.

It will be seen that salicylic acid alone acts inter alia as an anti-inflammatory, but that unexpectedly it also acts with the combination of ingredients in the example according to the invention to reduce significantly the inflammatory behaviour of each of these ingredients. This synergistic behaviour is totally unexpected and permits the formulation of products according to the invention such as the one tested which have a broad range of active ingredients to deal with traumas arising from every stage in the lifecycle of a specific acne event or related skin inflammation.
